Decks are about £8 from most places, but if you wanted to have a learner game I have several. Just shout. Me, Alan, Mike and Dave all have decks so there's no shortage of people to have a bash with.

The only other things you need are a few tokens for damage, stuns etc and something to represent 3 keys. Again, we have plenty of stuff between us. I've been using Imperial Assault tokens and keys I just printed out as cards.
